dawn of war
because you cannot turtle against a competent foe, its dynamic, fast and with a slew of different races and different play styles you can field a range of different strategies and ploys, because you use squads not individual units you can command a coherent battlefield and you need to to play well, its a game unforgiving to the slow however, and you need to attack to win, a turtle may foil a bot, but not a human with decent experience.
that said, its also beautiful like a gold plated cheerleader in lingerie.
ok, scrap the gold plating... and the lingerie.
awesome
P.S: each race must be played differently also, which makes for interesting team matches.
